RHD big single E82 135i
 
Mods in signature.
Cars been off the road attempting to fix it for 18months.
No idea what's wrong yet.
Thinking of replacing or rebuilding my engine 30k miles on it.
I'm considering the Gen2 PT 5558.
Rods pistons bearings.
Should i stay jb4/bef with pi controller or go standalone Haltech and custom flash?
Any suggestions would be sweet!

*EDIT* The shop with my car has a 9 sec 335i street registered N54. N55-N54 swap is not out of the question.

I’ve been running a precision 6266 gen2 for over 2.5 years now on my stock motor RHD N55.
Since installing the M4 flywheel, been able to run 28psi consistently with no issues. On the very limit on my dodson superstock clutches. Making 650whp+.

If you are going single, why not put the biggest one that can fit bottom mount? 6266
You can go with rods pistons for peace of mind but don’t think standalone is necessary.

Awesome! :)

This is exactly the kind of post i wanted to see. :happy
The shop think 6266 may be a bit big?
That is actually the turbo i asked them about installing.

No tuning issues at all?

Thx a million!

Its a tight fit but definitely one that is workable. Since the m4 flywheel the car has been running great. Send me an email on zaid661(at)gmail(dot)com as I’m not too clued up with adding pics and logs on the forum.

Can you please share what tune and fueling setup you are running?

houtan 01-07-2019 11:18 AM

op, good luck on the build. look forward to seeing how it progresses.

Jb4 with custom mhd backend flash. For fueling its fuel it stage 3 lpfp and pi running e85

Thanks Mate.

Cars in shop but having serious problems identifying what on earth is wrong with it. Latest parts to be replaced will be the valvetronics.

which symptons or codes ?

Ecu parameter knock codes and internal fueling codes were the original ones.
These indicated replacing the ecu, which I did, which did nothing.
I beleive the car now has some valvetronic codes but I'm not certain which ones and I dont want to pester the shop because the cars a nightmare and they'll probably ask me to collect and burn it.

Issue was:
Car puts down 465whp 25psi on dyno dynamics shootout dyno, graph is perfect , logs are immaculate across the board.
Once the car comes up to running temp I get a huge shut down at around 4k rpm like air fuel and spark all stop. I mean it's extreme. Like ejected thru windshield extreme.
It appears as well once up to temp even normal driving is affected, car breaks down and cant be used for anything other than very short trips. As mentioned once cool everything is perfect.
Car is now stock other than PI paltinum kit (not wired) turbo and FW.
It's not tuning related.

Oh also, someone on here advised me to take it to the dealer, they don't know what's wrong and told the shop to burn it.
I've also emailed Terry about it (and we know he's a very clever guy) his words were "push it off a cliff"

Had you read codes after that happens ?
You must replicate the situation where the car produce that huge shut down log and read codes.
Sometimes a $0.75 part could make $50,000 machine stop working propperly.

Granite66 01-11-2019 10:03 AM

Thanks to terry and my local tuner SR Speedworx

Yeah mate we reproduced the issue and read codes a million times.
Swapped nearly all the sensors, no love. There is really no indication in the logs or codes as to what is actually going on.

I think its time for new motor.

Same but the shop is worried it may still not fix the problem.

I'd like to buy a wrecker motor and do as per post 1.

JacquesN55 01-14-2019 10:20 PM

You could have bent rods or something in that line. Maybe blow by when car is warm.

Yes:( , I believe the ecu only sees knock when the car is warmed up so very possible. Valvetronic shaft and associated parts have all been ordered by the shop so I have my fingers crossed.

I’m running the speedtech kit at 600-650 daily. Been 6 months at least. 75k miles. I would go stand alone if it was possible but not sure I would want to be the first. Stand alone makes tuning so much more flexible.

I plan to build a n55 maybe later this year. Simple rods, gas ported and coated pistons, n54 cranks, etc.

Cool!

You're really happy with your car I assume?

Stoolz 01-21-2019 11:44 PM

I just bought a crashed 235. Gonna steal the engine out and sell off the spares with my mechanic.

JacquesN55 01-22-2019 03:13 AM
